Could anyone please tell me that if they have suffered the same problem as me the other day.I was approaching a roundabout at a bottom of a steep hill, braked well in advance, but my brake pedal almost touched the floor and the car jerked very violently to an almighty stop. As i carried on round the corner my brake pedal seemed very soft.I am hoping to have a look at the weekend, perhaps anyone may know that whether the servo is at fault or maybe the master cylinder. I have no brake fluid leaks as far as I can see.

I wouldn't point at the servo, but master cylinder is possible. Or a leak somewhere where you do not notice. Fortunately I have never experienced that problem, but this kind of failure is obviously not something you want to drive around with.

Thanks Anders once again, but i have only driven the car a short distance since the problem occurred. But now I am not even sure that it is a problem with the brakes. Because my pedal seems to be ok, but when i do brake the whole of the front of the car is very noisy and when i apply full lock onto the steering i can hear some heavy rubbing noise as if my drive shaft is struggling to turn. I am going to have a look at it over the weekend and in the mean time stop using it in case my steering / drive shafts are the culprits.
